An international human rights group is calling on Thailand's ruling military to end what it says is a "disturbing pattern of repression" in the country.

Amnesty International made the appeal in a report Thursday on the state of human rights in the Southeast Asian nation since the army seized power in a May coup.

The group says 665 people have been summoned or detained by the junta so far, mostly political opponents, academics, activists and others who have protested peacefully.

Although most were released within a week, Amnesty criticized the fact they were detained without charges or trials and have been forced into silence.

The group says it has also received credible reports of torture, allegations the junta has denied.
